  • How to implement DisplayMemberPath for my Wpf UserControl?

    - by Bevan
    I'm writing a WPF User Control for my application, wrapping a ListBox and a few other items. The ListBox has a new ItemTemplate that presents four pieces of information for each item in my list. I can hard code each of the four bindings to specific properties on my list items and they display fine. However, I want my UserControl to be a bit more flexible. On ListBox and ComboBox there is a property DisplayMemberPath (inherited from ItemsControl) that seems to "inject" the appropriate property binding into the standard ItemTemplate. How do I achieve the same result with my user control? I'd like to set up four new properties to allow configuration of the information displayed: public string LabelDisplayPath { get; set; } public string MetricDisplayPath { get; set; } public string TitleDisplayPath { get; set; } public string SubtitleDisplayPath { get; set; } Reviewing ItemsControl.DisplayMemberPath with Reflector seems to go down the rabbit hole, I haven't been able to fathom how it works. Also, if I'm completely off course - and there's another, more "WPF" technique that I should be using instead, please point me in that direction.

  • Force scope bar below UISearchBar

    - by axiixc
    I have a UISearchBar and UISearchDisplayController, everything works great but my scope selector displays beside the text field instead of below it. I know that this is the expected action when the device is in landscape, but since I have the UISearchBar in the master view of a UISplitViewController it ends up looking like this http://cl.ly/BN9 Is there any way to force the scope bar to display below the text field in all interface orientations (I know that this works nicely in Mail.app on the iPad, so its possibly, but who knows if Apple decided to hide the option to do so)

  • Silverlight TemplateBinding to RotateTransform

    - by Trog Dog
    I am trying to create the simplest Silverlight templated control, and I can't seem to get TemplateBinding to work on the Angle property of a RotateTransform. Here's the ControlTemplate from generic.xaml: <ControlTemplate TargetType="local:CtlKnob"> <Grid x:Name="grid" RenderTransformOrigin="0.5,0.5"> <Grid.RenderTransform> <TransformGroup> <RotateTransform Angle="{TemplateBinding Angle}"/> <!-- This does not work --> <!-- <RotateTransform Angle="70"/> --> <!-- This works --> </TransformGroup> </Grid.RenderTransform> <Ellipse Stroke="#FFB70404" StrokeThickness="19"/> <Ellipse Stroke="White" StrokeThickness="2" Height="16" VerticalAlignment="Top" HorizontalAlignment="Center" Width="16" Margin="0,2,0,0"/> </Grid> </ControlTemplate> Here's the C#: using System.Windows; using System.Windows.Controls; namespace CtlKnob { public class CtlKnob : Control { public CtlKnob() { this.DefaultStyleKey = typeof(CtlKnob); } public static readonly DependencyProperty AngleProperty = DependencyProperty.Register("Angle", typeof(double), typeof(CtlKnob), null); public double Angle { get { return (double)GetValue(AngleProperty); } set { SetValue(AngleProperty,value); } } } }

  • BindException with INTERNET permission requested

    - by Mondain
    I have seen several questions regarding SocketException when using Android, but none of them cover the BindException that I get even with the INTERNET permission specified in my manifest. Here is part of my manifest: <uses-permission android:name="android.permission.INTERNET"></uses-permission> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.READ_OWNER_DATA"></uses-permission> <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> <uses-permission android:name="android.permission.ACCOUNT_MANAGER"></uses-permission> <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS"></uses-permission> Here is the relevant portion of my LogCat output: 04-22 14:49:06.117: DEBUG/MyLibrary(4844): Address to bind: 192.168.1.14 port: 843 04-22 14:49:06.197: WARN/System.err(4844): java.net.BindException: Permission denied (maybe missing INTERNET permission) 04-22 14:49:06.207: WARN/System.err(4844): at org.apache.harmony.luni.platform.OSNetworkSystem.socketBindImpl(Native Method) 04-22 14:49:06.207: WARN/System.err(4844): at org.apache.harmony.luni.platform.OSNetworkSystem.bind(OSNetworkSystem.java:107) 04-22 14:49:06.217: WARN/System.err(4844): at org.apache.harmony.luni.net.PlainSocketImpl.bind(PlainSocketImpl.java:184) 04-22 14:49:06.217: WARN/System.err(4844): at java.net.ServerSocket.bind(ServerSocket.java:414) 04-22 14:49:06.227: WARN/System.err(4844): at org.apache.harmony.nio.internal.ServerSocketChannelImpl$ServerSocketAdapter.bind(ServerSocketChannelImpl.java:213) 04-22 14:49:06.227: WARN/System.err(4844): at java.net.ServerSocket.bind(ServerSocket.java:367) 04-22 14:49:06.237: WARN/System.err(4844): at org.apache.harmony.nio.internal.ServerSocketChannelImpl$ServerSocketAdapter.bind(ServerSocketChannelImpl.java:283) 04-22 14:49:06.237: WARN/System.err(4844): at mylibrary.net.PolicyConnection$PolicyServerWorker.(PolicyConnection.java:201) I Really hope this is a simple problem and not something complicated by the fact that the binding is occurring within a worker thread on a port less than 1024. Update Looks as if this is a privileged port issue, anyone know how to bind to ports lower than 1024 in Android? SelectorProvider provider = SelectorProvider.provider(); try { ServerSocketChannel channel = provider.openServerSocketChannel(); policySocket = channel.socket(); Log.d("MyLibrary", "Address to bind: " + device.getAddress().getAddress() + " port: 843"); InetSocketAddress addr = new InetSocketAddress(InetAddress.getByName(device.getAddress().getAddress()), 843); policySocket.bind(addr); policySocket.setReuseAddress(true); policySocket.setReceiveBufferSize(256); } catch (Exception e) { e.printStackTrace(); }

  • TimHeuer's FloatableWindow Issue

    - by MarioEspinoza
    Hi, I've some trouble with Tim's FloatableWindow. (<--SourceCode & DLLs) It throws the following Exception once closed the control. Object reference not set to an instance of an object in System.Windows.Controls.FloatableWindow.b__0(Object s, EventArgs args) in System.Windows.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args) in MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName) First I created a control by using the FloatableWindow template, And then i just created the Window on CodeBehind. private void Button_Click_1(object sender, RoutedEventArgs e) { FloatableWindow1 f1 = new FloatableWindow1();//TheTemplatedOne f1.ShowDialog(); } private void Button_Click_2(object sender, RoutedEventArgs e) { FloatableWindow f = new FloatableWindow(); f.Height = 100; f.Width = 100; f.Background = new SolidColorBrush(Colors.Yellow); f.ShowDialog(); } But stills the same issue... Im not trying to access any information on the Closed EventHandler. Im running v3.0.40624.4 Release of the dll on SL v3.0.50106.0 in a C# project w/RiaServices Thanks

  • iPhone: Execute code after animation of UIDeviceOrientation change finishes

    - by carloe
    Not sure if I can explain this correctly, but I am trying to execute a method device orientation animation finishes. Right now I have [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil];, but that triggers instantly. Is there a way to have it call didRotate after the view rotation animation is completed? Thanks!

  • Asynchronously populate datagridview in Windows Forms application

    - by dcryptd
    howzit! I'm a web developer that has been recently requested to develop a Windows forms application, so please bear with me (or dont laugh!) if my question is a bit elementary. After many sessions with my client, we eventually decided on an interface that contains a tabcontrol with 5 tabs. Each tab has a datagridview that may eventually hold up to 25,000 rows of data (with about 6 columns each). I have successfully managed to bind the grids when the tab page is loaded and it works fine for a few records, but the UI freezes when I bound the grid with 20,000 dummy records. The "freeze" occurs when I click on the tab itself, and the UI only frees up (and the tab page is rendered) once the bind is complete. I communicated this to the client and mentioned the option of paging for each grid, but she is adament w.r.t. NOT wanting this. My only option then is to look for some asynchronous method of doing this in the background. I don't know much about threading in windows forms, but I know that I can use the BackgroundWorker control to achieve this. My only issue after reading up a bit on it is that it is ideally used for "long-running" tasks and I/O operations. My questions: How does one determine a long-running task? How does one NOT MISUSE the BackgroundWorker control, ie. is there a general guideline to follow when using this? (I understand that opening/spawning multiple threads may be undesirable in certain instances) Most importantly: How can I achieve (asychronously) binding of the datagridview after the tab page - and all its child controls - loads. Thank you for reading this (ahem) lengthy query, and I highly appreciate any responses/thoughts/directions on this matter! Cheers!

  • Preloading Winforms

    - by msarchet
    I am currently working on a project where we have a couple very control heavy user controls that are being used inside a MDI Controller. This is a Line of Business app and it is very data driven. The problem that we were facing was the aforementioned controls would load very very slowly, we dipped our toes into the waters of multi-threading for the control loading but that was not a solution for a plethora of reasons. Our solution to increasing the performance of the controls ended up being to 'pre-load' the forms onto a hidden window, create a stack of the existing forms, and pop off of the stack as the user requested a form. Now the current issue that I'm seeing that will arise as we push this 'fix' out to our testers, and the ultimately our users is this: Currently the 'hidden' window that contains the preloaded forms is visible in task manager, and can be shut down thus causing all of the controls to be lost. Then you have to create them on the fly losing the performance increase. Secondly, when the user uses up the stack we lose the performance increase (current solution to this is discussed below). For the first problem, is there a way to hide this window from task manager, perhaps by creating a parent form that encapsulates both the main form for the program and the hidden form? Our current solution to the second problem is to have an inactivity timer that when it fires checks the stacks for the forms, and loads a new form onto the stack if it isn't full. However this still has the potential of causing a hang in the UI while it creates the forms. A possible solutions for this would be to put 'used' forms back onto the stack, but I feel like there may be a better way.

  • Best Practices for Setup and Management of an Open Source Project

    - by VirtuosiMedia
    Later this year I want to release a PHP framework that I've been working on as open source. I do use source control (SVN), but it's on an extremely limited basis. I'm self-taught, I develop by myself and don't have the experience of working with large teams. I have some ideas about what can help make a project successful, but I'm fuzzy on some of the details. Since it's not yet released, I want to do everything I can to set up the right infrastructure from the beginning. What do I need to know in order to setup and manage a successful project? Some ideas that I have to make it successful (beyond marketing it): Good documentation and tutorials Automated unit tests and builds to push update to the website A clear roadmap Bug Tracking integrated with the source control A style guide to keep the code consistent along with clear A forum for the community to get support, share ideas, etc. A good example application built with the framework A blog to keep the community informed Maintaining backwards compatibility wherever possible Some of my questions: How do I setup and automate a one step submit-test-commit-generate API docs-push update to website process? How do I handle (technically) submissions from other users? How can I ensure that those submissions must be approved before being integrated? What are some of the pitfalls that can be avoided in terms of the project community? I'd prefer to have it be as friendly and helpful as possible without a lot of drama. I'd love to learn from your experience on any of these points. If you think I'm missing anything big, please share that as well. Any resources (preferably geared toward a beginner) that you could point me towards would also be greatly appreciated.

  • Preventing iframe caching in browser

    - by Zarjay
    How do you prevent Firefox and Safari from caching iframe content? I have a simple webpage with an iframe to a page on a different site. Both the outer page and the inner page have HTTP response headers to prevent caching. When I click the "back" button in the browser, the outer page works properly, but no matter what, the browser always retrieves a cache of the iframed page. IE works just fine, but Firefox and Safari are giving me trouble. My webpage looks something like this: <html> <head><!-- stuff --></head> <body> <!-- stuff --> <iframe src="webpage2.html?var=xxx" /> <!-- stuff --> </body> </html> The var variable always changes. Despite the fact that the URL of the iframe has changed (and thus, the browser should be making a new request to that page), the browser just fetches the cached content. I've examined the HTTP requests and responses going back and forth, and I noticed that even if the outer page contains <iframe src="webpage2.html?var=222" />, the browser will still fetch webpage2.html?var=111. Here's what I've tried so far: Changing iframe URL with random var value Adding Expires, Cache-Control, and Pragma headers to outer webpage Adding Expires, Cache-Control, and Pragma headers to inner webpage I'm unable to do any JavaScript tricks because I'm blocked by the same-origin policy. I'm running out of ideas. Does anyone know how to stop the browser from caching the iframed content?

  • How do I get the User Entered Value in AjaxControlToolkit ComboBox when the enter key is pressed?

    - by Jason
    The Problem: The user entered value is missing in the .Text attribute of the AjaxControlToolkit ComboBox when the enter key pressed. Also the “on change” events events are not called but I am not using postbacks anyway so I do not care. Example: private void BuildFileListDetails(NHibernateDataProvider _providerM) { int resultsPage = Convert.ToInt32(ddlNavPageNumber.Text); const int RESULTS_PAGE_SIZE = 100; // The cbFileName.Text equals "" Not what user entered string searchFileName= cbFileName.Text; var xrfFiles = _providerM.GetXrfFiles(searchFileName, resultsPage, RESULTS_PAGE_SIZE); gvXrfFileList.DataSource = xrfFiles; gvXrfFileList.DataBind(); } My Solution: I needed to access the AjaxToolkit "ComboBox" imbedded TextBox control's .Text to access the value entered by user. private void BuildFileListDetails(NHibernateDataProvider _providerM) { int resultsPage = Convert.ToInt32(ddlNavPageNumber.Text); const int RESULTS_PAGE_SIZE = 100; string searchFileName; //The Solution: Access the AjaxToolkit "ComboBox" imbedded TextBox control's .Text to access the value entered by user. TextBox textBox = cbFileName.FindControl("TextBox") as TextBox; if (textBox != null) { searchFileName = textBox.Text; //textBox.Text = "User Entered Value" } else { searchFileName = cbFileName.Text; } var xrfFiles = _providerM.GetXrfFiles(searchFileName, resultsPage, RESULTS_PAGE_SIZE); gvXrfFileList.DataSource = xrfFiles; gvXrfFileList.DataBind(); }

  • C# winforms: graphics.DrawImage problem

    - by Tony
    Hi, I have a really strange problem with Graphics.DrawImage method. I have the PictureBox control in the Panel control with AllowScroll property = true. The program cuts the image on small parts basing on the area selected by the user. I load the image 300x547 and select the area (the red rectangle): program properly cuts the image: then, I load another image 427x640: and then, as the result I see that the image is not cut properly. Each img.jpg file has properly width & height but the drawn image is too small: here's the code snippet - it saves the bitmap area selected by the user: Bitmap bmp = new Bitmap(selectedAreaRECT.Width, selectedAreaRECT.Height); Graphics g = Graphics.FromImage(bmp); g.DrawImage(OriginalIMG, 0,0, selectedAreaRECT, GraphicsUnit.Pixel); g.Save(); g.Dispose(); bmp.Save(AppDomain.CurrentDomain.BaseDirectory + @"\Temp\" + "img1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg); As You see, the code is the same for the img1.jpg from image A and from Image B. I'm trying to resolve that stupid problem for too long, I don't know what's the reason of that problem. I tried diffrent constructors of the DrawImage method, with no success
